Definitions

  • the inner liner and flow director 50 Positioned within the first filter media 20 is an inner liner and flow director 50.
  • the inner liner and flow director 50 includes second filter media 52. This second filter media 52 is selected to coalesce water present within fuel flowing through the filter element 10.
  • the inner liner and flow director 50 also includes a flow channel 54 configured to direct fluid, primarily fuel and coalesced water that has passed through the second filter media 52.
  • this flow channel 54 is open along an interior side.
  • the top 55 and bottom 56 of the flow channel 54 are open, although the top is typically sealed by the top end cap 30 with potting compound and the bottom 56 in endcap 60.
  • the media can alternatively be adhered to the end caps with a thermal bonding process or other process, including a combination of various processes.
  • the sides 57, 58, 59 of the flow channel are typically solid surfaces that do not permit the flow of fluid across them.
  • the bottom 56 of the flow channel 54 is generally open, as will be described below, to permit flow of collected water out through bottom end cap
  • Figure 8B is a top cross sectional view of a portion of a filter element constructed and arranged in accordance with an implementation of the invention, the cross sectional view showing a core manifold 70B and separator 72B.
  • the separator 72B includes two panels of hydrophobic material 74B and 75B.
  • Figure 26 is an example seal assembly 600 constructed and arranged in accordance with an implementation of the invention, showing a first sealing portion 610 and a second sealing portion 620.
  • This construction can be used, for example, with the base plate 340 shown in Figure 23 and 24 or base plate 440 shown in Figure 25A and 25B .
  • the first sealing portion 610 engages around a central portion of the standpipe, while the second sealing portion 620 engages the top of the drain seal.
  • the first and second sealing portions 610 and 620 are shown integrally formed, but it will be understood that in some implementations the two portions can be separately formed and installed separately.
  • the integral formation of the first and second sealing portions reduces the number of parts used, aids in installation, and keeps the second seal retained within the slot (such as slot 350) into which it is inserted.
  • Figure 28 is an example seal assembly 800 constructed and arranged in accordance with an implementation of the invention, showing a first sealing portion 810 and a second sealing portion 820.
  • This construction can be used, for example, with the base plate 340 shown in Figure 23 and 24 or base plate 440 shown in Figure 25A and 25B .
  • the first sealing portion 810 engages around a central portion of the standpipe, while the second sealing portion 820 engages the top of the drain seal.
  • the first and second sealing portions 810 and 820 are shown integrally formed, but it will be understood that in some implementations the two portions can be separately formed and installed separately.
  • the integral formation of the first and second sealing portions reduces the number of parts used, aids in installation, and keeps the second seal retained within the slot (such as slot 350) into which it is inserted.
  • Figure 29 is an example seal assembly 900 constructed and arranged in accordance with an implementation of the invention, showing a first sealing portion 910 and a second sealing portion 920.
  • This construction can be used, for example, with the base plate 340 shown in Figure 23 and 24 or base plate 440 shown in Figure 25A and 25B .
  • the first sealing portion 910 engages around a central portion of the standpipe, while the second sealing portion 920 engages the top of the drain seal.
  • the first and second sealing portions 910 and 920 are shown integrally formed, but it will be understood that in some implementations the two portions can be separately formed and installed separately.
  • the integral formation of the first and second sealing portions reduces the number of parts used, aids in installation, and keeps the second seal retained within the slot (such as slot 350) into which it is inserted.
